DEVICE FOR VIEWING AND MAGNIFYING LINES IN TELEPHONE AND OTHER DIRECTORIES, &c'.

Application filed August Specification of- Letters Patent.

Patented Jan. 20, 1914. e, 1913. Serial No. 783,334.

a telephone directory over the line of a subscribers district number, name, etc., that may be the subject of a call so as to magnify the same and make it highl visible, and retain the place thereof for further reference thereto.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to'the specific arrangement and organization shown and described.

Figure 1 represents a perspective view of a telephone directory line viewer and magnifier embodying my invention. Fig. 2 represents a bottom plan thereof. Fig. 3 represents a transverse vertical section on line ww Fig. 1. Fig. 4 represents a transverse vertical section on line y-y Fig. 1. Fig. 5

represents a transverse vertical section of another embodiment of the invention.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings :1 designates a block or body of transparent material preferably glass, the top of which is convex in upward direction formin the lens 2 on said body. On the undersi e of the block there are coverings or coatings 3 of material which are on opposite sides of a centrally disposed rib 4, which is an integral portion of the block 1 and transparent the same as said body, while the portions of the bottom occupied by the material 3 is opaque in its nature, so as not to be possible of being seen through, but the rib 4 as is evident while being bordered by said coverin or coating allows unobstructed passage of light to and through its bottom after passing through the body of the block..

The block is placed as an optical instrument on a page of a telephone book, so that the rib 4 is over a line of rinted matter embodying the district num er, name, address,

etc. to be called, it being seen that said matter is highly magnified so that it can be viewed by the eyes through the lens with greater perspicuity than in its normal condition. Then the call is made while the block remains on the book at the set place after the manner of a paper weight, so that if the call is to be repeated, the lace or line originally selected and magni ed may be observed again at a glance without necessarily directing the eye here and there over the page to find the selection.

It will be noticed that the rib is clear glass similar to the body 1, and the portion of the bottom on opposite sides of said rib are opaque or rendered non-transparent and obscured, due to the coatings or coverings 3, and thus as the lens, body and rib are transparent, or in other words, the device is transparent from top to bottom through the lens, body and rib, only the selected line on the book is presented to the eye through the body of the block and lens thereon, thus avoiding confusion with or perceiving adj acent lines.

The bottom is recessed on opposite sides of the rib 4 so as to receive the covering or coating material 3 which thus borders said rib, thus raising said material and removing it from wearing or rubbing contact with the book.

It is evident that the device is serviceable similar for a telegraphic code book, dictionary, account book, etc.

In Fig. 5 I show a lens superimposed on a glass block and fused therewith, the result, however, being the same as in the previous figures.

It is desirable in all cases to form the body transparent from side to side and end to end, so that the light will reach the rib 4 through said body and so produce the best effects of illuminating the same, in reading off the matter on which the rib is placed.

Having thus described my invention what I claim as new and desire to secure by Let ters Patent, is

l. A viewer and magnifier of the character stated composed of a body, and a lens thereon, said body having a portion entirely transparent therethrough in vertical direction, and another portion aside of said transparent portion opaque, the transparent portion being in the line of vision of said lens.

2. A viewer and magnifier of the character stated composed of a body of transparent material having at the bottom a portion which is transparent with said body, and another port-ion is obscured, and a lens on said body in the line of vision of the portion that is transparent through said body and bottom.

3. A viewer and magnifier of the character stated composed of a block of transparent material, and a lens thereon, said body having a portion of the base opaque, lanai another portion transparent with said L A viewer and magnifier of the character stated composed of a block of transparent material, and a lens thereon, said body having a portion transparent from top to bottom, and other portions bordering said transparent portion.

5. A viewer and magnifier of the character stated composed of a body of trans parent material, a lens on the top of said body and a rib on the bottom thereof, said rib and body and lens being transparent through each other, the portion of the bottom unoccupied by said rib being opaque.

6. A viewer and magnifier of the character stated composed of a body of transparent material, a lens on the top of said body, and a rib on the bottom thereof, said rib, bodyand lens being transparent through each other, the portion of the bottombordering said rib being recessed and rendered opaque.
